Question

what does a scatter plot display?
a. the relationship between three variables
b. the distribution of a single variable
c. the average value of a dataset
d. the relationship between two different sets of data

Explanation:

A scatter plot uses dots to represent the values of two different variables. Each dot's position on the x - axis and y - axis corresponds to the value of one variable and the other variable respectively. By looking at the pattern of these dots (e.g., if they form a line - like pattern, a curve - like pattern, or are randomly scattered), we can understand the relationship (such as positive correlation, negative correlation, or no correlation) between the two sets of data.

• Option a: A scatter plot is for two variables, not three.
• Option b: A histogram or a box - plot is more suitable for showing the distribution of a single variable.
• Option c: A measure like the mean (average) is calculated numerically, not shown by a scatter plot.

Answer:

d. The relationship between two different sets of data
